each. Recently AGHARKAR ! has extended the details of this 
otk for arid north-west India. BiarrerR anp Hatiprre? 
have described the vegetation of the Indian Desert on the 
basis of WaRmiNa’s * formations, and SAxTON AND Sep@wick * 
have a the same for Gujarat. Kenoyer® has made a 
study of successions in the subtropical forests of the middle 
Braticyas, and I ® have madea similar type of study of the 
Gangetic Plains vegetation. Hor’ has studied the ecology 
of grasses in relation to forest types and iater*, has empha- 
sized the importance of ecological studies in solving problems 
of grazing land and forest management, and in the control of 
plant diseases. Other work is reported at this meeting, and is 
in progress, and the outlook for ecology in India is bright. 
The broad principles of ecology have been derived from 
studies on the vegetation of temperate regions. It is not vet 
known how generally these principles apply to the tropics. 
One botanist has put it, “ a large part of the plant eee 
(in India) should be studied without trying to fit them into a 
European or American system. Much study will be ‘requied 
whole.”” Brown * expresses a similar doubt: “...- meas 
from temperate regions are too apt to soaaitl temperate vege- 
tation as a generalized type and_ tropical vegetation as a 
specialized one, whereas there certainly are eeany reasons re 
p- 
action of the dense agricultural Rides ecology offers
